Subject: [PATCH v1 tty-next 0/4] 8250: microchip: Burst Mode Support for PCI1XXXX

This patch series improves the UART performance in PCI1XXXX from C0 rev
using burst mode operation. Each transaction processes DWORDs at a time
and the remaining bytes are handled byte-by-byte. With burst mode access
the baud rate support is extended from 1.5 Mbps to 3.9 Mbps.
